Electricity (Ex): The touch attack of a shocker inflicts 1d6 points of electrical damage. This damage is dealt to the shocker as well.

Shocking Discharge (Ex): If touched with bare flesh (including being struck in combat with a fist or claw) or metallic weapon, the shocker delivers 1d8 points of damage the attacker. This is true whether or not the attack is capable affecting the shocker. The damage it inflicts is subtracted from the shocker's hit-point total as well.

Immunities (Ex): Shockers are immune to mind-influencing effects, poison, paralysis, stunning and disease. They're not subject to critical hits, subdual damage, ability damage, or energy drain.
